Sump Pump Check Valves
Keep water from returning to the
sump pit or crawl space after the pump shuts off with a Sump Pump Check Valve. Keeping the basin or crawl space free of water and preventing backflow is vital, and a sump pump check valve allows for easy pump service without cutting any pipe. We also offer
Swing Check Valves, which are compression mount and provide an easy solution to servicing the pump without cutting pipe, plus there is no messy glue to set before testing or using the pump. For other check valves,

Frequently Asked Questions
Q. "Why are spring check valves not commonly used for sump and sewage installations?"
A. Some spring check valves have a center spring and shaft that can snare particles or debris and cause the check valve to not properly close.
